Math page 340 what number would you multiply the dividend and divisor by to make 5.72 divide 0.52 easier to divide?

Lilit [14]

Answer:

Multiply both the divisor and the dividend by 10 to make it easier to divide

Step-by-step explanation:

As given division equation in a more suitable format that shows the dividend and the divisor that is = $\frac{5.72}{0.52}$

so now we we will make the two parts to be whole number

first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places

so, that we multiplying both of them by a 10 will make them whole numbers

so so correct answer is 10

$\frac{5.72\times 10}{0.52 \times 10} =$ 11
