Answer: 20 origami frogs.

Step-by-step explanation: This is simple proportion problem

Number of origami frogs made in 36 minutes = 8

Therefore we first need to solve for number of origami frog Nina can made in 1 minute

                                                                       36 minutes = 8

                                                                       1 minute      = 8/36

                                                                                           = 2/9 origami frogs  

Therefore, in 90 minutes , Nina will make                       = 2/9 × 90/1

                                                                                           = 20 origami frogs.

Nina can make 20 frogs at the given rate in 90 minutes.

What do we mean by Proportion?

Proportion is a method where we show that one ratio will be equal to another ratio.

How do we solve the problem?

In the problem, we are given that Nina makes 8 origami frogs in 36 minutes, that is, the rate at which Nina is making origami frogs = 8/36.

We are asked to find out how many origami frogs will Nina make at the same rate. If we suppose she makes n number of frogs in 90 minutes at the same rate, then by Proportion, we get

n/90 = 8/36

or, n = (8*90)/36 = 20

∴ Nina can make 20 frogs at the given rate in 90 minutes.
