= 38/10 − 276/100

= 38/10 × 10/10 − 276/100

= 380/100 − 276/100

= ((380 - 276))/100

= 104/100

= 1.04

Subtract 9.398 from 34.65

Subtraction of decimal numbers - Part 3

= 3465/100 − 9398/1000

= 3465/100 × 10/10 − 9398/1000

= 34650/1000 − 9398/1000

= ((34650 - 9398))/1000

= 25252/1000

= 25.252

Subtraction of Decimal NumbersTo subtract decimal, first we convert them into fractions and then we cannot the final fraction into decimal. Subtract 2.76 from 3.8 2.76 from 3.8 3.8 – 2.76 = 38/10 − 276/100 = 38/10 × 10/10 − 276/100 = 380/100 − 276/100 = ((380 − 276))/100 = 104/100 = 1.04 Subtract 9.398 from 34.65 9.398 from 34.65 34.65 – 9.398 = 3465/100 − 9398/1000 = 3465/100 × 10/10 − 9398/1000 = 34650/1000 − 9398/1000 = ((34650 − 9398))/1000 = 25252/1000 = 25.252
