Answer:
Step-by-step explanation:
Given:
27 + 2/3 ÷ 3 + 9/10
In division, compatible numbers are numbers that can be divided mentally.
27 + 0.67 ÷ 3 + 0.9
27.67 ÷ 3.9
= 7.0948717948717
Approximately
= 7
But, alternatively
27.67 is closer to 28
3.9 is closer to 4
Therefore,
28 ÷ 4
The quotient of 27 + 2/3 ÷ 3 + 9/10 using compatible numbers is around 7
true and false
The answer are B and C
-5² + 50 = 25
|2 x 5| = 10
y = -7(-13)
=> y = -7 × (-13)
= y = 91
