Suppose I am in a store buying a shirt, a tie, and slacks. Each of the prices ends in 99 cents, and it is hard to add the exact amounts in my head. I can make an estimate, and decide if this is too much to spend or not.

Wht is 84 is 74% of what number
Elina [12.6K]
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.
