1. some third - grade students visited the science exhibit. the number of the visitors was 632. one hundred forty - seven more parents visited the science exhibit. how would you determine how many of the visitors were adults?

① 632 + 147 = n
② 147 - 632 = n
③ 147 + n = 632
④ 632 - n = 147

Explanation:

Question 5

Step1: Define division components

We have dividend $47$, divisor $9$. We calculate $47 \div 9 = n$, remainder $r$.

Step2: Calculate quotient and remainder

$9\times5=45$, $47-45=2$. So remainder $r=2$.

Step1: Define total and student count

Total visitors: $147$, students: $63$. Adults = Total - Students.

Step2: Match to equation

Adults $n = 147 - 63$, which rearranges to $63 + n = 147$.

Step1: Define division components

Dividend $89$, divisor $11$. Calculate $89 \div 11 = n$, remainder $r$.

Step2: Calculate quotient and remainder

$11\times8=88$, $89-88=1$. Remainder is $1$ foot.

Answer:

2
