Which expression shows how Joshua could use place value to break up this problem and solve it?(1 point) Responses (31+7)×(11+1) open paren 31 plus 7 close paren times open paren 11 plus 1 close paren (30+8)×(10+2) open paren 30 plus 8 close paren times open paren 10 plus 2 close paren (32+6)×(10+2) open paren 32 plus 6 close paren times open paren 10 plus 2 close paren (30+8)×(11+1)

Answer 1

To find the product of 38 × 12 using place value, Joshua can break down the numbers into their place values.

For 38, we can break it down as follows:

• 30 (the tens place)
• 8 (the ones place)

For 12, we can break it down as follows:

• 10 (the tens place)
• 2 (the ones place)

Thus, the expression that shows how Joshua could break up the problem and solve it using place value is:

(30 + 8) × (10 + 2)

So the correct response is:
(30 + 8) × (10 + 2).
