Answer:
Step-by-step explanation:
Give the ratio of red to green to blue marbles to be 3:5:7
Total ratio = 3+5+7 = 15
Total marbles = 600marbles
Amount of red = ratio of red/total ratio × 600
Amount of red marbles = 3/15 × 600
Amount of red marbles = 3×40 = 120marbles
Amount of green marbles = 5/15×600
Amount of green marbles = 5×40 = 200marbles
Amount of blue marbles = 7/15×600
Amount of blue marbles = 7×40 = 280marbles
Answer:
B.
Step-by-step explanation:
number of ounces = n
number of pounds = p
There are 16 ounces in 1 pounds (unite rate: 1 pounds = 16 ounces)
Therefore, there would be n ounces in p pounds
Set a proportion to find n.
16 : 1 = n : p
Multiply both sides by p
Answer:
7/20
Step-by-step explanation:
Convert them so they have the same denominator.
1/4 + 1/10
A common denominator is 40 (I'm just choosing an easy one for now, rather than the smallest one)
1/4 * 10/10 = 10/40
1/10 * 4/4 = 4/40
10/40 + 4/40
Add the numerators
(10 +4)/40 = 14/40
Simplify the fraction
14/2 = 7 40/2 = 20
7/20
