What is Ratio?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
Given that;
40 identical machines in a factory pack 180 crates of oranges per day
So,
a) The ratio of the number of machines to the number of crates packed per day is:
40/180 = 1:4.5
b) crates of oranges would 90 of these machines pack per day is
40/180 = 90/x
x = 4.5 x 90
x = 405
