Answer:
The sum of 17.7, 9.8 and 35.5 is 63
Step-by-step explanation:
First lets find the sum of 17.7 and 9.8
9.8 = 10 - 0.2
17.7 + 9.8
= 17.7 + (10 - 0.2)
= 27.7 - 0.2
= 27.5
Now lets add 27.5 and 35.5
35.5 = 33 + 2.5
27.5 + 35.5
= 27.5 + 33 + 2.5
= 30 + 33
= 63
The sum of 17.7, 9.8 and 35.5 is 63
