Answer:
The missing addend is 1/20
Step-by-step explanation:
Variable x: missing addend
4/10 + x = 45/100
When adding or subtracting fractions, the denominators must be the same number.
To convert 10 to 100, we must multiply 10 by 10.
If we multiply 10 to the denominator, we must do the same to the numerator (multiply by 10).
4 × 10 / 10 × 10
40/100
Use this fraction in the equation now
40/100 + x = 45/100
Now isolate the variable, x, by subtracting 40/100 from both sides
40/100 - 40/100 + x = 45/100 - 40/100
When subtracting fractions, only subtract the numerators. The denominators remain the same
x = 5/100
Simplify 5/100
Both numbers can be divided by 5
5 ÷ 5 / 100 ÷ 5
1/20
