a.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $67 + x=142$, so $x = 142 - 67=75$.
Answer:
75
b.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $100 - x = 33$, so $x=100 - 33 = 67$.
Answer:
67
c.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $52x = 364$, so $x=\frac{364}{52}=7$.
Answer:
7
d.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $\frac{x}{16}=83$, so $x = 83\times16 = 1328$.
Answer:
1328
e.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $19 + x+23 + 82=206$. First, add the known numbers: $19+23 + 82=124$. Then $x=206 - 124 = 80$.
Answer:
80
f.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $10\times x\times5 = 400$. First, simplify the left - hand side: $50x = 400$. Then $x=\frac{400}{50}=8$.
Answer:
8
g.
Explanation:
Step1: Solve for the missing number
Let the missing number be $x$. Then $750\div x = 30$, so $x=\frac{750}{30}=25$.
Answer:
25
