Please answer this ASAP! Alma completed 5/8 of the homework assignment. If there were 32 problems, how many problems did Alma complete?

Respuesta :

semsee45

Answer:

20

Step-by-step explanation:

Let [tex]x[/tex] = the number of problems Anna completed

Using ratios

                                      5 : 8 = [tex]x[/tex] : 32

                                            [tex]\frac{5}{8} =\frac{x}{32}[/tex]

Cross multiply:           5 x 32 = [tex]x[/tex] x 8

                                       160 = 8[tex]x[/tex]

Divide both sides by 8:   20 = [tex]x[/tex]

Therefore, Anna completed 20 problems.
