= 2 + (8 + 2/4 x 1/10)
= 2 + [(8/4 + 2/4 ) x 1/10]
= 2 + [(2 + 2/4) x 1/10]
step 7 Repeat the step 5 to find the decimal equivalent for the fraction 2/4 in the above expression:
= 2 + [(2 + 2/4) x 1/10]
= 2 + [(2 + 0.5) x 1/10]
= 2 + (2.5 x 1/10)
= 2 + 2.5/10
= 2 + 0.25
step 8 Find the sum of above expression:
= 2 + 0.25
= 2.25
