Sure! Let's solve this problem step by step.
1. We are given three numbers: [tex]\(a = 90\)[/tex], [tex]\(b = 5\)[/tex], and [tex]\(c = 2\)[/tex].
2. First, we need to find the sum of [tex]\(b\)[/tex] and [tex]\(c\)[/tex].
[tex]\[
b + c = 5 + 2 = 7
\][/tex]
3. Next, we divide [tex]\(a\)[/tex] by the sum we calculated in the previous step.
[tex]\[
\frac{a}{(b + c)} = \frac{90}{7} \approx 12.8571
\][/tex]
4. Thus, the sum of [tex]\(b\)[/tex] and [tex]\(c\)[/tex] is [tex]\(7\)[/tex], and when we divide [tex]\(90\)[/tex] by [tex]\(7\)[/tex], we get approximately [tex]\(12.8571\)[/tex].
Therefore, the answers are: [tex]\(b + c = 7\)[/tex] and [tex]\(\frac{90}{7} \approx 12.8571\)[/tex].
