Answer:
\(52\frac{5}{8}\) inches
Step-by-step explanation:
We are given that brad grew \(4\frac{1}{4}\) inches this year and now height of brad is \(56\frac{7}{8}\) inches
We have to write an equation for finding of height of Brad and find the height of brad at the start of this year.
Let x be the height of Brad at the start of this year
According to question
\(x+4\frac{1}{4}=56\frac{7}{8}\)
\(x+\frac{17}{4}=56 \frac{7}{8}\)
\(x=\frac{455}{8}-\frac{17}{4}\)
\(x=\frac{455-34}{8}\)
\(x=\frac{421}{8}\)
\(x=52\frac{5}{8}\)
Hence, the height of brad at this year =\(52\frac{5}{8}\) inches
