a. 7 / 10 x 5 = 35/10 (small = 3 a.m. to 1 p.m. / 2)
ReplyDeleteb. 1 / 2 x 1 / 3 = 1 / 6 (multiply, multiply the numerator and denominator)
c. 3 feet = 36 inches
36 from 3 xdivided / 4 = 36 x 4 / 3
36 x 4 / 3 = 144 / 3 (reduction = 48)
a.
ReplyDeleteW = 7 / 10 x L
and,
L = 5
so,
W = 7 / 10 x 5
W = 7 / 2 inches
b.
Cake eaten = 1 / 3 * 1 / 2 = 1 / 6
Fraction of the whole cake = 1-1/3-1/6 = 1 / 2.
So I ate half the cake!
c.
First you should know that there is a foot 12 inches.
Now,
3 feet = 3 x 12 = 36 inches
How far 3/4inch = 36 / (3 / 4) = 48 pounds
HPE this helps!
a) W = (* 7 / 10) L then W = (7 / 10) * 5 = 35/10 = 3.5 "
ReplyDeleteb) 1 / 3 * 1 / 2 = 1 / 6
c) = 36inch 3feet, then 36 / (3 / 4) = 36 * 4 / 3 = 144 / 3 = 48 pounds
