Answer:

15/20

Step-by-step explanation:

1. Take the denominator of 3/4 and multiply it by 5 because that is what it takes to get 20 from 4.

4 x 5 = 20.

2. Multiply the numerator by 5 as well.

15/20

How to do 15 1/2 - 2 1/10 how to do it

lisov135 [29]

First, you need to make the fractions have the same denominator:

15 1/2 ---> 15 + (1/2 x 5) = 15 5/10

2 1/10 ---> 2 1/10

Then you need to subtract them from each other:

15 5/10

<u>- 2 1/10</u> (or) 15 5/10 - 2 1/10 = 13 4/10

13 4/10

This gets the answer: <u>13 4/10</u>

The photo printed has length of 6 imams width of 4. A smaller picture is printed the ratio of the new picture to the size of the

Serggg [28]

We know the width of the first picture, is 4
we know the ratio from smaller to larger is 1.5:2

thus $\bf \cfrac{\textit{width of small}}{\textit{width of large}}\qquad 1.5:2\implies \cfrac{1.5}{2}=\cfrac{w}{4}$

solve for "w".

we know the length of the first picture, 6

$\bf \cfrac{\textit{length of small}}{\textit{length of large}}\qquad 1.5:2\implies \cfrac{1.5}{2}=\cfrac{L}{6}
$

solve for "L".

The division is using extra zeros.
2 * 16 = 32, but 3200 was placed below 3426.

Now 1 * 16 = 16, so 160 goes below 226.
The number that goes in the box is 160.
