a boy spend 2/7 of his pocket money on transport and 1/5 on sweet. what fraction of his pocket money does he spend on transport and sweet?
2 / 7 + 1 / 5 =
2 * 5 / ( 7 * 5 ) + 1 * 7 / ( 5 * 7 ) =
10 / 35 + 7 / 35 =
17 / 35
17/35
Please how did you get the answer
please we dont understand it oo
7/35
I'm sorry for the mistake in my previous answer. Let me explain the solution step by step:
The boy spends 2/7 of his pocket money on transport and 1/5 on sweets. To find the fraction of his pocket money that he spends on both transport and sweets, we need to find the sum of these two fractions.
We can't add these fractions directly because they have different denominators. So, we need to find a common denominator for them. The least common multiple of 7 and 5 is 35.
Now, we need to convert both fractions into fractions with a denominator of 35:
2/7 = (2/7) x (5/5) = 10/35
1/5 = (1/5) x (7/7) = 7/35
So, the boy spends a total of 10/35 + 7/35 of his pocket money on transport and sweets:
10/35 + 7/35 = 17/35
Therefore, the fraction of his pocket money that he spends on transport and sweets is 17/35.
To find the fraction of pocket money that the boy spends on both transport and sweets, we need to find the common denominator for the fractions 2/7 and 1/5.
The least common multiple (LCM) of 7 and 5 is 35.
To convert the fractions with denominators of 7 and 5 to a common denominator of 35, we can multiply the numerator and denominator of each fraction by factors that will result in a denominator of 35.
For the fraction 2/7:
2/7 * 5/5 = 10/35
For the fraction 1/5:
1/5 * 7/7 = 7/35
Now we can add the fractions together:
10/35 + 7/35 = 17/35
Therefore, the boy spends 17/35 of his pocket money on both transport and sweets.
