Question

Jada’s teacher ask her to write a three-digit number that uses the digit 4 once and the digit 7 twice. The value of one 7 needs to be 1/10 the value of the other 7. What number can jada write?

Answer 1

477

The value of the first 7 from the left is 70.

If you divide 70 by 10, you get the value of the second seven, 7.

Another way to know this is equivalent fractions:

1/10 = 7/10

10 X 7 = 70
1 X 7 = 7
