What is 3 and 5/9 subtracted by 1 and 7/8

2 answers:

5 0

First off we change the mixed numbers into an improper fraction.
This is how we do it
denominator x whole number + numerator.
9 x 3 + 5 = 32/9
8 x 1 + 7 = 15/8
Now we can multiply.
15 x 32 = 480
8 x 7 = 56
480/56
Since this is an improper fraction we have to change it to a mixed number
This is how we do it
numerator ÷ denominator
480 ÷ 56 = 8 32/56
8 32/56 simplified = 8 4/7
The answer is 8 4/7

I hope this helps!

40/9. you have to simply it and make it an inproper fraction so it would be 224/63 - 504/63 which simplifies to 40/9.

Answer: BX = 7

======================================

Explanation:

For any rectangle, the diagonals are the same length and they cut each other in half (aka bisect each other).

This means diagonal BD = AC = 14 and BX = BD/2 = 14/2 = 7. The value of AB is never used.

A car travels along a straight road for 30 seconds starting at time t = 0. Its acceleration in ft/sec2 is given by the linear gr

I am Lyosha [343]

From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

$\frac{(10)(10)}{2}+ \frac{(20)(20)}{2}=250 ft/sec^{2}$

Hence, the distance is 250×30=7500 ft

Answer:

Whole #'s: All natural numbers plus 0

Integers: Whole numbers and their opposites

Rationals: Can be expressed as ratios, repeating numbers, decimals, so on.

-2/5 is a fraction or ratio, meaning it doesn't belong in whole NOR integer.

-2/5 belongs in the rationals box.

-7.8 is negative, but it is a decimal, so it belongs in the rationals box.

1/10 is not a whole, not an integer, but a rational number.

13 is a whole number, integer, and rational, so it belongs in the whole box.

10 is also a whole number grouped under the categories given.

-5 is the opposite of 5, and whole numbers aren't negative, so -5 belongs in the integers box.

-8/4 is a fraction, not considering its simplified form that would give -2, so it belongs in the rationals box.

We know there are 208 pages in total. On Monday, she read 3/8 of the pages. This can be demonstrated as 208 * 3/8, which is 78. 208-78 = 130.

We know there are 130 pages left. On Tuesday, she reads 28 pages. 130-28=102

We know there are 102 pages left. On Wednesday, she read 1/4 of the total pages. 1/4 (of) 208 is 1/4*208, that is 52.

To know how many pages are left, we subtract her read pages from the remaining pages. 102-52 = 50.

Amanda has 50 pages left until she finishes the novel.

Hope this helped.

James answered 14 items correctly on a 16-item quiz. what percent did he answer correctly?

Troyanec [42]

So,

I like to simplify a fraction first. This is what I do when I'm in a store trying to find the unit price.

$\frac{14}{16}$

Factor.
$\frac{2*7}{2*2*2*2}$

Cross out ones.
$\frac{7}{2*2*2}$

Multiply it out.
$\frac{7}{8}$

In my head, I remember that one-eighth is equal to 0.125.

So seven-eighths is equal to 0.125 times 7.
0.125 * 7 = 0.875

Convert to percent form.
0.875 --> 87.5%

James answered 87.5% of his quiz correctly.

I actually have the decimal equivalents for eighths in my head when I'm shopping. So once I get seven-eighths, I immediately know how much that is. I can also subtract 0.125 from 1.000 to get seven-eighths.
