Question

select all of the equations in which the remainder is 3
a ( 51 div 8 = 6 \text{ r}7 )?

b ( 481 div 9 = 53 \text{ r}7 )?

c ( 1,258 div 5 = 251 \text{ r}7 )?

d ( 2,227 div 6 = 371 \text{ r}7 )?

e ( 3,180 div 9 = 353 \text{ r}7 )?

Explanation:

Step1: Verify A's remainder

Calculate $8×6 + 3 = 51$, so $51÷8=6\ R3$. Correct.

Step2: Verify B's remainder

Calculate $9×53 + 3 = 489 + 3 = 492≠481$. Incorrect.

Step3: Verify C's remainder

Calculate $5×251 + 3 = 1255 + 3 = 1258≠1256$. Incorrect.

Step4: Verify D's remainder

Calculate $6×371 + 3 = 2226 + 3 = 2229≠2227$. Incorrect.

Step5: Verify E's remainder

Calculate $9×353 + 3 = 3177 + 3 = 3180$. Correct.

Answer:

A. 51 ÷ 8 = 6 R3, E. 3180 ÷ 9 = 353 R3
