Answer:
12.57 is the circumference when the diameter is 4.
Step-by-step explanation:
The decomposition of the fraction A = 8/10 is solved and
a) A = 2/5 + 2/5
b) B = 5/10 + 3/10
A fraction can be expressed as the product of a whole number and a unit fraction. Decomposition of fraction means break down a fraction into smaller parts. The denominator which is the bottom number gives the total number of pieces
Given data ,
To decompose 8/10 in two ways, we need to find two pairs of fractions that add up to 8/10
First way:
We can write 8/10 as 4/5, and then decompose 4/5 into two fractions with a common denominator. One way to do this is to split 4/5 into two equal fractions:
8/10 = 4/5 = 2/5 + 2/5
Another way to decompose 8/10 is to split it into a sum of a whole number and a fraction that is less than 1. We can write 8/10 as 0.8, and then decompose it into 0.5 and 0.3:
8/10 = 0.8 = 0.5 + 0.3
Second way:
We can also decompose 8/10 in a different way. We can write 8/10 as the sum of two fractions with a common denominator, where one of the fractions is a unit fraction (a fraction with a numerator of 1):
B = 5/10 + 3/10
Hence , the decomposition of the fraction A = 8/10 is solved
