Answer :
Let's solve the missing numbers step by step.
a) [tex]_ \div 6 = 72[/tex]
To find the missing number, we need to perform the inverse operation of division, which is multiplication:
[tex]_ = 72 \times 6[/tex]
[tex]_ = 432[/tex]
b) [tex]490 - _ = 276[/tex]
To find the missing number, use the inverse operation of subtraction, which is addition:
[tex]_ = 490 - 276[/tex]
[tex]_ = 214[/tex]
c) [tex]16 \times _ = 80[/tex]
To find the missing number, use the inverse operation of multiplication, which is division:
[tex]_ = 80 \div 16[/tex]
[tex]_ = 5[/tex]
d) [tex]\frac{32}{40} = _[/tex]
Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 8:
[tex]\frac{32}{40} = \frac{32 \div 8}{40 \div 8} = \frac{4}{5}[/tex]
e) [tex]_ \text{ seconds} = 25 \text{ minutes}[/tex]
Since there are 60 seconds in a minute, convert minutes to seconds:
[tex]_ = 25 \times 60[/tex]
[tex]_ = 1500 \text{ seconds}[/tex]
f) [tex]\frac{12}{687} \text{ m/ } _ \text{ m}[/tex]
This seems to be missing context, so it's unclear what is required here.
g) [tex]0.5 \text{ km} = _ \text{ m}[/tex]
Since 1 kilometer equals 1000 meters, convert the kilometers to meters:
[tex]0.5 \times 1000 = 500 \text{ m}[/tex]
