1. Check divisibility for 72 ÷ 3<br /> Calculate $72 \div 3 = 24$. Since the result is an integer, it is divisible.<br /><br />2. Check divisibility for 125 + 10<br /> Calculate $125 + 10 = 135$. Check if 135 is divisible by any specific number (not provided). Assuming a common divisor like 5, $135 \div 5 = 27$, which is an integer. So, it is divisible by 5.<br /><br />3. Check divisibility for 98 ÷ 7<br /> Calculate $98 \div 7 = 14$. Since the result is an integer, it is divisible.<br /><br />4. Check divisibility for 144 + 12<br /> Calculate $144 + 12 = 156$. Check if 156 is divisible by any specific number (not provided). Assuming a common divisor like 6, $156 \div 6 = 26$, which is an integer. So, it is divisible by 6.<br /><br />5. Check divisibility for 200 ÷ 9<br /> Calculate $200 \div 9 \approx 22.22$. Since the result is not an integer, it is not divisible.
