Krista's softball team played 35 games this season and lost only 7 of them.What percent of their games did Krista's team lose?

Answers

The fraction $(7)/(35)$ represents how many games Krista's softball team lost out of the 35 games Krista's team played.

To find the percent of games that Krista's team lost, we need to turn the fraction $(7)/(35)$ into a percent.

We can reduce $(7)/(35)$ by dividing both the numerator and denominator by the Greatest Common Factor of 7 and 35 using 7.

7 ÷ 7 = 1

35 ÷ 7 = 5

Now, we have our reduced fraction.

1 ÷ 5 = 0.2

0.2 × 100 = 20%

Therefore, Krista's softball team lost 20% of their games.

A packet of candles and a box of matches cost ₦420. The candles cost 6 times as much as the matches. Find the cost of the matches.Please show the workings.
Thanks

Answers

Let's say
cost of packet of candles = a

cost of box of matches = b

Total cost = 420
a + b = 420

cost of candles = 6 times of cost of box of matches
a = 6 * b
a = 6b

a + b = 420
6b + b = 420
7b = 420
b = 60

so cost of matches = 60

x - price of candles
y - price of matches

x+y=420
x=6y

6y+y=420
7y=420
y=60

Matches cost ₦60.
