Question

Express 1.18 as a mixed number

Answer 1

Write the decimal number as a fraction
(over 1)
1.18 = 1.18 / 1

Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's

Numerator = 1.18 × 10 × 10 = 118
Denominator  = 1 × 10 × 10 = 100

Numerator / Denominator = 118 / 100

Simplifying our fraction

= 118/100

= 59/50

= 1  9/50

Answer 2

Answer: 1 and 18/50

Step-by-step explanation: Using the place value chart, we can see that 1.18 is 1 unit, 1 tenth, and 8 hundredths. Think of one one-tenth and eight-hundredths  as 18/100 so we have 1 and eighteen-hundredths which can be written as the mixed number 1 and 18/100.

We can reduce 18/100 by dividing both the numerator and denominator by 2 and we will get 9/50.

Therefore, 1.18 can be written as the mixed number 1 and 9/50.
