A scientist studies a group of left-handed people. In the study, there are 10 left-handed males for every 8 left-handed females.
a. Complete the ratio table.
\begin{tabular}{c|c|c|c|c|c|}
& & & 20 & 25 & \
\hline Number of Left-Handed Males & 10 & & & & 24
\end{tabular}
b. Describe the ratio relationship by using the addition patterns in the table.
If there are 40 left-handed males in the study, how many left-handed females are there?
Answer (3)
To determine how many 5/9s are in 1, we divide 1 by 5/9, which is equivalent to multiplying 1 by the reciprocal 9/5. Thus, there are 1.8 or 9/5 lots of 5/9 in 1. ;
In order to find out how many 5/9 are in 1 whole, we should write the following equation: x * 5/9 =1 where x is the number of 5/9 5 x/9=1 5 X=9 X=9/5=5/5 + 4/5= 1 4/5 So, in 1 whole there are 1 whole 5/9 and 4/5 from 5/9.
There are \\\frac{9}{5} or 1 \\\frac{4}{5} parts of \\\frac{5}{9} in 1. This means that in one whole, you get 1 complete part of \\\frac{5}{9} and an additional \\\frac{4}{9}.
