First, find the number of shaded blocks.
shaded blocks = 8 × 3
shaded blocks = 24
There are 24 shaded blocks
Second, find the number of the blocks
all blocks = 8 × 10
all blocks = 80
There are 80 blocks in total.
Third, write a fraction defining the shaded blocks compare to the blocks in total
fraction = 24/80
simplify
fraction = 3/10
Fourth, change the fraction into percent
Percent means per hundred. Change the denominator to 100
fraction = 3/10
percent = (3 × 10) / (10 × 10)
percent = 30/100
percent = 30%
The percentage of the blocks shaded in the picture is 30%
1/2, 8/18 = 4/9, which is close to 4/8 wich is equal to 1/2
Can you attach the image of the table ?
7x-3y=15 is the equation in standard form.
