Allana used Fraction 3 over 5 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 7 over 10 yard

Delvig [45]

Answer:

Step-by-step explanation:

Divide 1 7/10 by 3/5 to see if the quotient is greater than 2. If it's not, you can't get 2 scarves out of it. If it is, then you can get 2 scarves out of it and have whatever the remainder is as left-over. Before we divide, let's change that 1 7/10 into an improper fraction since it will be easier to work with.

1 7/10 = 17/10

Now we can divide:

$\frac{\frac{17}{10} }{\frac{3}{5} }$

The rule for dividing fractions is that you bring up the lower fraction and flip it to multiply, so that looks like this:

$\frac{17}{10}$ × $\frac{5}{3}$

To simplify before we multiply, we can reduce between the 5 and the 10 and have smaller numbers to deal with:

$\frac{17}{2}$ × $\frac{1}{3}$

The product there is $\frac{17}{6}=2\frac{5}{6}$

So the answer you want from your choices is

"Yes, because the quotient of Fraction 1 and 7 over 10 [division sign]Fraction 3 over 5 is 2 and 5 over 6", third choice

Izzie recently took a math test where each correct answer was worth 8.7 points. She also correctly answered a bonus question wor

harina [27]

Let's use x as the number of questions she answered correctly. If we make an equation of out the question, it would be 8.7x+13=108.7 To solve the equation subtract 13 from both sides. So it will leave you with 8.7x=108.7-13, which is 8.7x=95.7. Divide both sides by 8.7, which will give you x=11. She answered 11 questions correctly.
