Answer:
100
Step-by-step explanation:
The distributive property: a(b + c) = ab + ac
127 × 32 = 127 × (30 + 2) = 127 × 30 + 127 × 2 = (130 - 3) × 30 + (130 - 3) × 2
=(130)(30) - (3)(30) + (130)(2) - (3)(2) = 3900 - 90 + 260 - 6
= 3810 + 254 = 4064
127 × 32 = (130 - 3) × 32 = 130 × 32 - 3 × 32 = 130 × (30 + 2) - 96
= (130)(30) + (130)(2) - 96 = 3900 + 260 - (100 - 4) = 4160 - 100 + 4
= 4060 + 4 = 4064
Dividing 3 by 0.1 tells how many tenths are in 3 ones.
3÷0.1 is the same as 30÷1, which is 30.
It takes 10 tenths to make 1 whole, so it will take 3 times 10 tenths to make 3 wholes. 3×10=30.
The quotient has 110 of the value of the dividend so the dividend must be 10 times greater.
The 3 in 30 is 1 place to the right of the 3 in the whole number 3 which increases the value of the number 10 times.

D.5x/12
You must divide the numerator and denominator by the great common multiple. The greatest common multiple of 25 and 55 is 5. 25 divided by 5 equals 5 (numerator), and 55x divided by 5 is 11x (denominator). Therefore the answer is A. 5/11x
