People can be left-handed, right-handed or ambidextrous. The number of boys in Canadian secondary schools who are left handed is about 1/7 the number of boys who are right-handed. About 11% of boys are left-handed. Write and solve an equation to determine what percent of boys are right-handed.
1/7 RH= LH
.11B= LH
setting them equal
1/7 RH=.11B
RH/B= ????
To solve this problem, we need to set up an equation based on the given information. Let's use the variable "x" to represent the percentage of boys who are right-handed.
According to the information given, the number of boys who are left-handed is about 1/7 the number of boys who are right-handed. This means that if we take 1/7 of the percentage of boys who are right-handed (x), we should get the percentage of boys who are left-handed.
The equation can be written as follows:
1/7 * x = 11%
To solve for x, we can multiply both sides of the equation by 7 to eliminate the fraction:
(1/7) * 7 * x = 11% * 7
x = 77%
Therefore, the percentage of boys who are right-handed (x) is 77%.
