Answer 2

Answer:

18.7 should be multiplied by 4 by 5 to get answer 15.

Step-by-step explanation:

Given information,

4 by 5 be multiplied by an number to get an answer of 15

We have to find out the number which should be multiplied by 4 by 5 to get answer 15.

Let, The required number is x.

So We can write given information as,

$\frac{4}{5} \times x = 15$

Shift 4/5 to right side it becomes 5/4

$x = 15 \times \frac{5}{4}$

$x = \frac{15 \times 5}{4}$

$x = \frac{75}{4}$

By dividing 75 by 4 we get

$x = 18.7$

Hence,

18.7 is the required number.

18.7 should be multiplied by 4 by 5 to get answer 15.
