Answer:
Time for the entire practice is 2.25 or 2 1/4 hours
Step-by-step explanation:
According to the question the volley ball coach daily plan practice includes stretching , scrimmaging and she use the remaining practice time working on drills of specific skills.
let the entire time required for practice = y minutes
Stretching consumes 10 minutes, mathematically
stretching = 10 minutes
scrimmaging = 2/3 × y
Drills of specific skills = y - (2/3 × y) - 10 = 1/3 y - 10 minutes
On Wednesday she had
stretching + scrimmaging = 100 minutes
we all know her stretching daily timing is 10 minutes and scrimmaging timing is 2/3 × y
Therefore,
10 + 2/3 y = 100
100 - 10 = 2/3 y
90 = 2/3 y
multiply both sides by 3
90 × 3 = 2/3 y × 3
270 = 2 y
y = 135 minutes
since the answer is suppose to be in hours
60 minutes = 1 hour
135 minutes = ?
135/60 = 2.25 hours or 2 1/4 hours
The ratios are called equivalent ratios, which have the same values.
Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given to name the two ratios that have the same value,
The ratios are called equivalent fractions,
Comparable to equivalent fractions are equivalent ratios. An equivalent ratio results from multiplying or dividing the antecedent (the first term) and the consequent (the second term) of a given ratio by a non-zero value.
for example, 1/3 is also written as 2/6, 3/9, and so on,
and each of them has a value equal to 1/3.
Hence the ratios are equivalent fractions.
