Answer 2

Answer:

Here is your answer:

$(50 + 15) =( 50 + 10 + 5) = (60 + 5)$

Step-by-step explanation:

5 tens + 15ones = 5 tens + 1 tens + 5 ones = 6 tens + 5 ones

》

$(5 \times 10) + (15 \times 1) = (5 \times 10) + (1 \times 10) + (5 \times 1) = (6 \times 10) + (5 \times 1)$

$= (50 + 15) = (50 + 10 + 5) = (60 + 5)$

$75 = 75 = 75$

Hence verified.
