L = 4 + w
l/w = 7/5
l = 7w/5
7w/5 = 5 + w
7w = 25 + 5w
2w = 25
w = 12.5
l = 4 + 12.5
l = 16.5
the dimensions are 16.5 x 12.5 cm
Answer:
There would have been three people in the group.
Step-by-step explanation:
This is because if you add 2/3 together until you get that amount, it will add up to having three people. If this sounds confusing, here is a visual thing to help.
2/3+2/3=4/3 which can also equal 1 1/3
1 1/3 + 2/3 =2
you added 2/3 together three times to get two, so three is the answer.
Hope this helps!
