There are 44 learners in Mart's class.the ratio of the number of boys to the number of girls is 5:6.how many boys are there in Mart's class?
let the number of boys be 5x and the number of girls be 6x
5x+6x=44
11x=44
x=4
so we have 20 boys and 24 girls
(notice 20:24 = 5:6)
To find the number of boys in Mart's class, you need to divide the total number of learners by the sum of the parts of the ratio representing the boys and girls.
First, calculate the total number of parts in the ratio: 5 + 6 = 11.
Next, divide the total number of learners by the total number of parts in the ratio and multiply the result by the number of parts representing the boys.
Number of Boys = (Total number of learners / Total number of parts) * Number of parts representing boys
Number of Boys = (44 / 11) * 5
Number of Boys = 4 * 5
Number of Boys = 20
Therefore, there are 20 boys in Mart's class.
To find the number of boys in Mart's class, we need to use the given ratio of 5:6 and the total number of learners in the class, which is 44.
Step 1: Calculate the total number of parts in the ratio. The ratio of boys to girls is 5:6, so the total number of parts is 5+6 = 11.
Step 2: Divide the total number of learners (44) by the total number of parts (11) to find the value of one part.
44 learners ÷ 11 parts = 4 learners per part.
Step 3: Multiply the value of one part by the number of parts representing boys (5) to find the number of boys in the class.
4 learners per part × 5 parts = 20 boys.
Therefore, there are 20 boys in Mart's class.
