Answer:

17

Step-by-step explanation:

54 has 4 ones

and 5 tens

37 has 7 ones

and 3 tens

subtracting ones

7 ones are taken from 54

so along with the existing 4, 1 ten is decreased and another 3 ones are decreased resulting in 7 ones now

now 54 has 5-1= 4 tens

subtracting tens we get 4-3=1

Therefore 1 ten and 7 ones

⇒ 17
