125−48
48 is the same as 12
= 125−12
125 is the same as 1+25
= 1+25−12
Now we need a common denominator. Multiply and divide 1 by 10 .
= 1010+25−12
Multiply and divide 25 by 2 .
= 1010+2∗25∗2−12
= 1010+410−12
Multiply and divide 12 by 5 .
= 1010+410−1∗52∗5
= 1010+410−510
10 apples + 4 apples - 5 apples = 9 apples So
10 tenths + 4 tenths - 5 tenths = 9 tenths
= 910
