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
I believe the equation shown above is an example of:
B. Associative Property of Addition.
Hope I helped!!
The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.
Expressing 2/7 as a decimal number will give;
2/7 = 0.2857142... (It gave repeated decimal values)
Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places
0.2857142 = 0.286 (to the nearest thousandth)
Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
