Sfiso wanted to work out the fraction of the day he spends sleeping and doing homework. he however, made the following mistake: 1/3 1/3 +1/8= 2/11
I don't mind helping to find answers, but I resent having to provide the questions as well.
To find the fraction of the day Sfiso spends sleeping and doing homework, we need to add the fractions correctly.
The correct calculation would be:
1/3 + 1/3 + 1/8
To add fractions with different denominators (3 and 8), we need to find a common denominator. In this case, the common denominator is 24 (3 x 8).
Now we can rewrite the fractions with the common denominator:
8/24 + 8/24 + 3/24
Adding the numerators, we have:
8 + 8 + 3 = 19
So the correct fraction of the day Sfiso spends sleeping and doing homework is 19/24, not 2/11.
To find the fraction of the day Sfiso spends sleeping and doing homework, he needs to add the fractions correctly.
The mistake Sfiso made was in his addition. Let's break it down step by step:
1/3 + 1/3 + 1/8
To add fractions, the first thing you should do is find a common denominator. In this case, the least common denominator (LCD) for 3 and 8 is 24.
1/3 can be converted to 8/24. To do this, we multiply the numerator and denominator of 1/3 by 8:
(1/3) * (8/8) = 8/24
1/8 can be converted to 3/24. To do this, we multiply the numerator and denominator of 1/8 by 3:
(1/8) * (3/3) = 3/24
Now that we have a common denominator for both fractions, we can add them together:
8/24 + 8/24 + 3/24 = (8 + 8 + 3) / 24 = 19/24
Therefore, the correct fraction of the day Sfiso spends sleeping and doing homework is 19/24, not 2/11 as he mistakenly calculated.
