If both fractions are from the whole:
1 - 2/7 - 1/5 = ?
You might want to change them to decimals to solve.
Right! Your method was better.
To find the fraction of pocket money that the boy has left, we need to subtract the fractions he spent on transport and sweets from the whole amount, which is represented by the fraction 1.
Step 1: Add the fractions spent on transport and sweets.
2/7 (spent on transport) + 1/5 (spent on sweets)
Step 2: Find a common denominator for the two fractions. In this case, the common denominator is 35.
To convert 2/7 to a fraction with a denominator of 35, we multiply the numerator (2) and the denominator (7) by 5:
(2/7) * (5/5) = 10/35
To convert 1/5 to a fraction with a denominator of 35, we multiply the numerator (1) and the denominator (5) by 7:
(1/5) * (7/7) = 7/35
Step 3: Add the converted fractions.
10/35 + 7/35 = 17/35
Step 4: Subtract the sum of the fractions from 1 to find the fraction left.
1 - 17/35 = (35/35) - (17/35) = 18/35
Therefore, the boy has 18/35 of his pocket money left.
