Find another name for the given number, but with the deniominator indicated. Use multiplication by 1.

2/7= ?/14

7 ? = 28

? = 4

I don't see what "multiplication by 1" gets you.

What did you get as the answear? and how did u get it?

I got 4, by cross-multiplying.

When a/b = c/d, ad = bc

To find another name for the fraction 2/7 with the denominator of 14, we can use the concept of equivalent fractions. Multiplying a fraction by 1, in the form of a fraction with the same numerator and denominator, will not change its value.

So, to change the denominator of 2/7 to 14, we can multiply both the numerator and the denominator by the same number. In this case, we want to multiply by a number that will result in a denominator of 14.

To go from 7 to 14, we multiply by 2 (14 ÷ 7 = 2). Therefore, we'll multiply the numerator and denominator of 2/7 by 2.

(2/7) x (2/2) = 4/14

Therefore, the fraction 2/7 is equivalent to 4/14 when the denominator is 14.
