The answer should be b) division because you are dividing three from both sides to get x by itself
Answer:
243 people
Step-by-step explanation:
Kelli is searching for a new daycare center for her child. At Lori's Local Daycare, there is a ratio of 2 caretakers for every 7 children. If there are 189 total children, then how many people are at the daycare facility?
The ratio is given as:
Caretakers : Children
2 : 7
= In fraction = 2/7
If there are 189 total children, then how many people are at the daycare facility?
Step 1
We calculate the number of caretakers is there are 189 children
7 children = 2 caretakeras
189 children = x
Cross Multiply
7x = 189 × 2
x = 189 × 2/7
x = 54 caretakers
Step 2
The total number of people at the daycare
= 189 children + 54 caretakers
= 243 people
Answer:
1/3
1/4
2/3
1/2
3/4
1/6
Step-by-step explanation:
Simply multiply each number by one-third.
1 * 1/3 = 1/3
3/4 * 1/3 = 3/12 = 1/4
2 * 1/3 = 2/3
1 1/2 = 3/2 * 1/3 - 3/6 = 1/2
2 1/4 = 9/4 * 1/3 = 9/12 = 3/4
1/2 * 1/3 = 1/6
Subtract b and then a = (zma) - b
