Answer:
400
Step-by-step explanation:
30 girls , 12 were selected
40 boys, 16 were selected
We can simplify these down by finding the Greatest Common Factor in both girls and boys:
30:12 .... 15:6 .... 1 : 2.5 30/12 .... 15/6 .... 2.5
40:16 .... 20:8 .... 1 : 2.5 OR 40/16 .... 20/8 .... 2.5
They are equal ratios because their most simplified ratios/fractions are equivalent
G-8=B you can't find out B (boys) until you know how many G (girls) there are in Mrs. Davis's class
Answer:
30 gallons
Step-by-step explanation:
step 1 right it out
2 hour is 120 mins and 4 cups are poured per min
step 2 Equation time
so your equation should be
4/1=x/120
step 3 solve it out
1 times 120 is 120 is 4 times 120 is 480
but that is not the answer 480 is the amount of CUPS that are used for 2 hrs
so all u have to do is now convert
step 4 convert
16 cups are in 1 gal. so divide 480 by 16 and get 30 gal
x=30 gallons
