Answer:
5/6
Step-by-step explanation:
1/3 + 1/2 = 5/6
Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
It is going to 21 because when you is divid 386÷18=21and you don't have 21 up there either I did it wrong or you do not have up there bc you missed up
8*4=32
7*4=28
340÷32=10.625
350÷28=12.5
12.5-10.625= 1.875
