The answer is 75 % you just have to divide 84 and 112 and u get 75%

Answer from: jjelzy

The question can be shown as
1.12 X ? = 84

"%" is "dividing by 100"
"of" is "multiplying"
"is" is "="

1.12 X ? = 84
Divide by 1.12 on both sides to get the value of the unknown.

84/1.12=75
So 112% of 75 is 84.

75 is the answer.

Answer from: Quest

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

Answer from: Quest

for this case we have that by definition, the surface area of a cylinder is given by:

$sa = 2 \pi * r * h + 2 \pi * r ^ 2$

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

$sa = la + 2ba$

where:

la: it's the lateral area

ba: area of the base

option a
