Question

2 which of the following equations are correct? select all that apply. a. 3144 ÷ 6 = 524 b. 57,290 ÷ 85 = 67 r4 c. 5612 ÷ 61 = 90 d. 1776 ÷ 37 = 48 e. 34,520 ÷ 40 = 863

Explanation:

Step1: Check Option A

Calculate \( 6\times524 \). \( 6\times500 = 3000 \), \( 6\times24 = 144 \), so \( 3000 + 144 = 3144 \). So \( 3144\div6 = 524 \) is correct.

Step2: Check Option B

Calculate \( 85\times67 + 4 \). \( 85\times60 = 5100 \), \( 85\times7 = 595 \), so \( 5100 + 595 = 5695 \), then \( 5695 + 4 = 5699
eq 57290 \). So this is incorrect.

Step3: Check Option C

Calculate \( 61\times90 = 5490
eq 5612 \). So this is incorrect.

Step4: Check Option D

Calculate \( 37\times48 \). \( 30\times48 = 1440 \), \( 7\times48 = 336 \), so \( 1440 + 336 = 1776 \). So \( 1776\div37 = 48 \) is correct.

Step5: Check Option E

Calculate \( 40\times863 = 34520 \). So \( 34520\div40 = 863 \) is correct.

Answer:

A. \( 3144 \div 6 = 524 \)
D. \( 1776 \div 37 = 48 \)
E. \( 34,520 \div 40 = 863 \)
