1. Mr. Perez’s pre-school class completed [tex]\frac{7}{8}[/tex]of their coloring papers, [tex]\frac{3}{4}[/tex] of their painting papers, and [tex]\frac{5}{4}[/tex] of their drawing papers. What expression could be used to find the total number of papers completed?

Respuesta :

Answer by JKismyhusbandbae: [tex]\frac{7}{8} + \frac{3}{4} + \frac{5}{8}[/tex]

Explanation: To find the sum total of completed papers, add the three values together.

apologiabiology

to find the total number of papers completed, add the number of papers completed together

add them by making same denomenator (bottom number)

to keep the numbers the same, multiply each fraction by 1 or a/a where a=a


see the denomenators

8,4,4

the least common multipule is 8 (8*1=8 and 4*2=8)


7/8 times 1/1=7/8

3/4 times 2/2=(3*2)/(4*2)=6/8

5/4 tiimes 2/2=(5*2)/(4*2)=10/8

so

7/8+3/4+5/4=

7/8+6/8+10/8=

[tex]\frac{7+6+10}{8}=[/tex]

[tex]\frac{23}{8}=[/tex]

[tex]\frac{8}{8}+\frac{8}{8}+\frac{7}{8}=[/tex]

[tex]1+1+\frac{7}{8}=[/tex]

[tex]2[/tex] [tex] and [/tex] [/tex]\frac{7}{8}[/tex] papers completed
