27 - 15 = 12
Adding 15 to both sides, we have,
27 - 15 + 15 = 12 + 15
i.e. 27 = 12 + 15
Answer: C [12 + 15 = 27]
To calculate by estimation, round each number to the nearest ten, hundred, ets as the case may be.
Here, rounding to the nearest ten, we have,
267 - 154 = 270 - 150 = 120.
Answer: C
Quotient of 18 and 2 = 18/2 = 9
Sum of 22 and 9 = 22 + 9 = 31
Subtracting the quotient of 18 and 2 from the sum of 22 and 9, we have:
31 - 9 = 22
Answer: D
19 weeks, 325-40=285 285/15=19
Answer:
40
Step-by-step explanation:
8 = x/5
x = 8*5
x = 40
Answer:
Writing the information in the form of ratio
Three point basket = Three point tries
3 : 4
27 : x
Think about multiplication , how many 3s do you need to make 27 ?
Its 27 ÷ 3= 9
Because you need 9 lots of 3, Then to make it proportional , you'd need 9 lots of 4
9×4 = 36
Three points tries is 36
