Question

For every left-handed person, there are about 6 right-handed people. If there are 70 passengers on a bus, predict the number of passengers who are right-handed.

A) 10
B) 20
C) 30
D) 40

Answer 1

Dividing the total number of bus passengers (70) by 7 gives 10 groups of one left-handed and six right-handed individuals. Multiplying the number of groups (10) by the number of right-handed individuals per group (6) gives us 60 right-handed passengers.

Step-by-step explanation:

To predict the number of passengers who are right-handed, we must use the ratio given that for every left-handed person, there are about 6 right-handed people. If there are 70 passengers on the bus, we first need to calculate the total number of groups of seven people each (one left-handed and six right-handed for each group). To do this, we divide 70 by 7, which equals 10. This gives us 10 groups, where each group consists of 1 left-handed and 6 right-handed individuals. Next, we multiply the number of groups by the number of right-handed individuals per group: 10 (groups) × 6 (right-handed individuals per group) equals 60 right-handed people. Thus, we can predict that there are 60 right-handed passengers on the bus.
