a man spends 1/4 of his monthly income on children's school fees and 3/5 on his home affair.what fraction of his come left
To find the fraction of the man's income left, we need to subtract the fractions he spends on children's school fees (1/4) and on his home affairs (3/5) from 1 (which represents the whole income).
First, let's find the common denominator for 4 and 5, which is 20.
1/4 = 5/20
3/5 = 12/20
Now we can subtract these fractions from 1:
1 - (5/20 + 12/20)
= 1 - (17/20)
= (20/20) - (17/20)
= 3/20
Therefore, 3/20 of his income is left.
To determine the fraction of the man's income that is left after spending on children's school fees and home affairs, we need to subtract the fractions spent from 1.
Let's calculate it step by step:
1. The fraction spent on children's school fees is 1/4.
2. The fraction spent on home affairs is 3/5.
To find the remaining fraction, we subtract the sum of the two fractions spent from 1:
1 - (1/4 + 3/5)
To subtract fractions, we need a common denominator. The least common multiple of 4 and 5 is 20. Therefore, we can rewrite the equation as:
(20/20) - (5/20 + 12/20)
Now, we can combine like terms:
20/20 - (5 + 12)/20
20/20 - 17/20 = 3/20
Therefore, the fraction of the man's income that is left is 3/20.
