(x-21)/4
x is the number subtract 21 and divide by 4
Answer:
4 1/12
Step-by-step explanation:
a = 5/6 b = 3 1/4 = 13/4
To add 5/6 + 13/4, we have to make the denominators the same:
20/24 + 78/24 = 98/24
To make it back to a mixed fraction:
4 2/24
4 1/12
B. 7 because 24 + 24 = 48 meaning 6 cars have been washed within 48 mins. 1 car can be washed in 8 mins. 48 + 8 = 56
Ok, so increasing a recipe originally for 16 to 24, you need to figure out how many times larger you need the recipe, so divide 24 by 16, and you get 1.5 (one and a half times larger)
You then just need to take each ingredient amount and multiply it by 1.5
2 cans chopped clams x 1.5 = 3 cans
4 cups broth x 1.5 = 6 cups
6 cups milk x 1.5 = 9 cups
4 cups cubed potatoes x 1.5 = 6 cups
Does this make sense?
1/8 + 2/3= 19/24
I/you have walked 19/24 miles total, since 19/24 can't be simplified.
