The components of an integer division are dividend, divisor, quotient and a remainder.
The expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60
Start by testing the options
[tex]\mathbf{362 \div 50}[/tex]
50 can divide 362 in 7 places and a remainder of 12.
So:
[tex]\mathbf{362 \div 50 = 7\ R\ 12}[/tex]
[tex]\mathbf{492 \div 50}[/tex]
50 can divide 492 in 9 places and a remainder of 42.
So:
[tex]\mathbf{492 \div 50 = 9\ R\ 42}[/tex]
[tex]\mathbf{420 \div 60}[/tex]
60 can divide 420 in 7 places and without a remainder
So:
[tex]\mathbf{420 \div 60 = 7}[/tex]
[tex]\mathbf{408 \div 60}[/tex]
60 can divide 408 in 6 places and with a remainder of 48
So:
[tex]\mathbf{408 \div 60 = 6\ R\ 48}[/tex]
[tex]\mathbf{502 \div 70}[/tex]
70 can divide 502 in 7 places and a remainder of 12.
So:
[tex]\mathbf{502 \div 70 = 7\ R\ 12}[/tex]
Hence, the expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60
