Option A: Decimal to percentage: x100
---------------------------------------------------
0.14 x 100 = 14%
--------------------------------------------------
Option 2: Fraction to percentage: x100
---------------------------------------------------
5/7 x 100 = 71.4%
--------------------------------------------------
Option C: Fraction to percentage: x 100
---------------------------------------------------
12/5 x 100 = 240%
--------------------------------------------------
Option D: Decimal to percentage: x 100
---------------------------------------------------
1.4 x 100 = 140%
--------------------------------------------------
Answer D
---------------------------------------------------
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

-(4/5)*(3/7)*(15/16)*(-14/9) [two negatives make one positive]
=(4*3*15*14)/(5*7*16*9) [simplify 4/16]
=(3*15*14)/(5*7*4*9)
=(3*3*14)/(7*4*9)
=(14)/(7*4)
=(2)/(4)
=1/2
