Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
One fourths divided by three is one twelfth. When dividing fraction remember to use reciprocation. 1/4 divided by 3 = 1/4 x 1/3 = 1/12. Hope this helps!
This is fraction multiplication. We need to find 1/5 of 2/3 of the cake.
Multiply numerator by numerator, and denominator by denominator:
1/5 x 2/3 =
(1x2)/(5x3) =
2/15
The answer is A. 2/15
