This is a situation where a "Please" would really help.

In the picture, I see a 12 being divided by 3/5 .

I'm sure you've learned how to divide by a fraction . . . you flip the fraction upside down, and then multiply by it.

So, if you need to divide 12 by 3/5, you'll need to flip the 3/5 upside down, then multiply the 12 by 5/3 .

Are you uncomfortable because you know how to multiply two fractions, but 12 is not a fraction so there's only one fraction here ? Is that what's troubling you, Bunky ?

What if I take the 12 and write it as 12/1 . I haven't changed it at all, but now it looks like a fraction ! So now the problem is: Multiply (12/1) x (5/3) .

Multiply the two numerators to get the numerator of the product.

Numerator is (12 x 5) = 60

Multiply the two denominators to get the denominator of the product.

Denominator is (1 x 3) = 3

So the product is 60/3 .

You could leave it like that. But I don't think the teacher would be happy, because 60/3 is crying out to be simplified.

It's 20 .

$\mathsf{Given :\;\;\dfrac{12}{\frac{3}{5}}}$

$\mathsf{:\implies 12 \times \dfrac{5}{3}}$

$\mathsf{:\implies 4 \times 5}$

$\mathsf{:\implies 20}$

Manny used 8 tenth-size parts to model 8/10. Ana used fewer parts to model an equivalent fraction. How does the size of a part i

e-lub [12.9K]

It should be bigger, think of a pie:
if you cut it into 2 parts, the pieces are big
if you cut it into 4 parts, the pieces are smaller

in both parts, the AMOUNT OF PIE stays the same, the size changes

here, we cut out 8 / 10 pieces, (manny)
ana has the same WHOLE amount, but in BIGGER pieces because she has an amount less than 8.

It works if you REDUCE THE FRACTION, 8/10 can be REDUCED to 4/5, Ana's pieces should be twice as big as Manny's, but she only has 4

Bobby has already ran 1 mile on his own, and he expects to run 1 mile during each track practice. How many track practices would

german

Answer:

In order to have ran 33 miles, Bobby would have to attend 32 track practices.

Step-by-step explanation:

Solving this problem entails of uncovering the amount of track practices Bobby must attend in order to have ran 33 miles. Start by reading the problem carefully to break down the information provided.

You can see that Bobby has already ran one mile on his own. This is important to remember for later. The problem also states that he expects to run one mile at every track practice.

Setting up an equation will help us solve. Here is how we could set up the equation:

(amount of miles already ran = 1) + (number of track practices = x) = (total miles to run = 33)

1 + x = 33

The equation is now in place. You can solve this, or isolate 'x', by using the subtraction property of equality. This means we will subtract one from both sides of the equation, thus isolating the variable.

1 + x = 33

1 - 1 + x = 33 - 1

x = 32

The variable is the only term left on the left side of the equation. This means Bobby must attend track practice 32 times in order to have ran 33 miles.

Brainliest to first answer correct.

suter [353]

Answer:

Option A is correct.

Step-by-step explanation:

The height of the rectangular pack is h1 = 4r

The height of the parallelogram = 2r + the height of equilateral triangles with a side of 2r

The height of equilateral triangle with a side of 2r = (side)/2*√3

=(2r)/2 *√3 = r√3

The height of the parallelogram h2 = 2r+r√3 = r(2+√3)

So,the ratio of h1 to h2 is :

4r : r(2 +√3)

Cancelling r we get

Hence, the ratio is 4 : 2 +√3

If angle 1 is 110°, what would the other angle measures have to be in order for m || n and

ra1l [238]

Answer:

Angle 2: 110 degrees, 1 and 2 would have to be the same for the lines to be parallel

Angle 3: 70 degrees angle 3 would have to be the complement to angle 1, so 1+3=180 and 70*3=180, so 3=70 degrees

Angle 4: 70 degrees, 3 and 4 have to be the same opposite angles for the lines to be parallel
