Answer:
#3 is 40
#4 is 90
Step-by-step explanation:
3/8 divided by 4/5 is the same as 3 * 5 / 8 * 4 = 15/32 or 0.46875
Answer:
r=9/2 or 4.5
Step-by-step explanation:
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get
r=9/2 or 4.5
3 1/4-11/3
31/4 simplifies to 13/4
So you now have 13/4-11/3
Which is -5/12
your final answer is -5/12
