Question

Fill in the blank:
4 tens + 3 tens + 2 ones + 5 ones =

• A. $67$
• B. $4325$
• C. $77$

Answer 1

The correct option is C $77$

Add the digits with the same place value! Start from the ones place.

2 ones + 5 ones = 7 ones
4 tens + 3 tens = 7 tens

Therefore,
4 tens + 3 tens + 2 ones + 5 ones
= 7 tens + 7 ones
= 77
