Because the decimal system is based on 10 ("decem" = 10 )
3/8 = 6/16 by multiplying the numerator and denominator by 2
0.12 = 3/25 Dividing by 8 is the same as multiplying by 1/8 => 3/25*1/8 = 3*1/25*8 = 3/200 (=0.015)
2/5, 4/10 and 44/110.In each case, dividing by 0.40 gives 1.
A rational number is, by definition, the answer from dividing one integer by another.
By dividing both the numerator and denominator by the same number is like dividing by 1.
by adding, subtracting, dividing, and multiplying.
There's not a lot to explain. They're different words for the same thing. When you're multiplying, you call them factors. When you're dividing, you call them divisors.
3/8 = 6/16 by multiplying the numerator and denominator by 2
Dividing a number is the same as multiplying by its multiplicative inverse. Ergo, they are the same if both numbers are 17.43.
0.12 = 3/25 Dividing by 8 is the same as multiplying by 1/8 => 3/25*1/8 = 3*1/25*8 = 3/200 (=0.015)

When dividing by fractions, multiply the whole number by the reciprocal of the fraction. In this case, it's the same as multiplying the whole number by the denominator. 5 divided by 1/2 = 5 x 2/1 = 10
True. Your question is self-explanatory. Multiplying any number by one produces the original number.
675 / 9 = 75 6.75 / 9 = 0.75 It is the same calculation, but it is 100 times smaller.
