Because you can simplify 40/100 and get 4/10
when you divide 40/100 by ten on the den. and num. you will get 4/10
8
6/8 = 3/4 pounds
Step-by-step explanation:
Step 1 :
From the number line we can see that
1 bag of grapes has weight of 1/8 pounds
4 bags of grapes has weight of 1/4 pounds
3 bags of grapes has weight of 3/4 pounds
Step 2 :
The total number of bags having a weight of minimum 3/8 pounds is 1 + 4 + 3 = 8
The total weight of bags that has weight of minimum 3/8 pound is
1/8 + 1/4 + 3/ 8
= 1/8 + 2/8 + 3/8 ( L.C.M is 8)
=6/8 =3/4 pounds

Answer:
The answer to your question is:
side 1 = 22.5 cm
side 2 = 30 cm
side 3 = 37.5 cm
Step-by-step explanation:
ratio = 3:4:5
Perimeter = 90 cm
First we get the sum of the numbers of the proportions
3 + 4 + 5 = 12
now divide the perimeter by the number of parts (12)
90 / 12 = 7.5
Side 1 = 3(7.5) = 22.5 cm
Side 2 = 4(7.5) = 30 cm
Side 3 = 5(7.5) = 37.5 cm
Perimeter = 22.5 + 30 + 37.5 = 90 cm
<span>The sum of angle D and the given angle should 90 so: 90 - 47 = 43
So D is 43.
