Answer:
Width of 10 cm, length of 22 cm
Step-by-step explanation:
P=2L+2w
64=2(12+w)+2w
64=24+2w+2w
40=4w
10=w
L=12+w
L=22cm
What is the easiest way to divide whole numbers to fractions?
Just follow these two easy steps:
1. Multiply the whole number to the denominator of the fraction. In other words, the bottom number of the fraction will be multiplied to the whole number, like this:
12 ÷ 6/7 = n
<u> 6 </u>
7 x 12
You will have 6/ 84.
2. Simplify.
6 = 1, 2, 3, 6
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 42, 84
the GCF is 6. divide both numbers by 6, so the answer will be 1/14.
You can also get the reciprocal and proceed to multiplication , like this: (12/1 is the fractional form or the whole number 12.)
1/12 x 6/7=n
that makes 6/84 or 1/14.
