<u>Answer:</u>

The correct answer option is D. He multiplied the divisor by 100 and dividend by 10.

<u>Step-by-step explanation:</u>

We are given that Miguel completed the division where initially he had to divide 754 by 0.52.

To make it easier, he multiplied both the divisor and the dividend by the same number to get rid of the decimal in the divisor.

If he multiplied the divisor by 100, he should have multiplied the dividend by 100 too. But instead, he mistakenly multiplied the divisor by 100 and dividend by 10.

Use unit multipliers to convert 50 square meters to square inches
Lady bird [3.3K]

50 square meters is equal to 77500 square inches

<em><u>Solution:</u></em>

Given that we have to convert 50 square meters to square inches

<em><u>Use the following conversion factor</u></em>

1 meter is equal to 39.3701 inch

That is,

1\ meter = 39.3701\ inch

<em><u>Now frame the conversion factor for square meters to square inches</u></em>

1\ meter\ \times meter = 39.3701 \times 39.3701\ inch\ \times inch\\\\1\ m^2 = 1550\ in^2

<em><u>Now convert 50 square meters to square inches</u></em>

Muliply both the sides by 50

1 \times 50\ m^2 = 1550 \times 50\ in^2\\\\50\ m^2 = 77500\ in^2

Thus 50 square meters is equal to 77500 square inches
