What percentages of these grids are shaded? a) b)

Step-by-step explanation:

a) 6 out of 10 are shaded. 6/10 = 60/100 so it is 60%

b) 11 out of 20 are shaded. 11/20 = 55/100 so it is 55%

a) is 60 percent and b) is 55 percent

Step-by-step explanation:

a) = 60 percent

First count up all the squares. That's 10 squares in total. Now count up all the squares that are shaded. That's 6. So the amount that's shaded is 6/10, but we need to find that in percentage, so we divide. 6 divided by 10 is 0.6, or 60 percent. The answer to a) is 60 percent.

b) = 55 percent

First count up all the squares. That's 20 squares in total. Now count up all the squares that are shaded. That's 11. So the amount that's shaded is 11/20, but we need to find that in percentage, so we divide. 11 divided by 20 is 0.55, or 55 percent. The answer to b) is 55 percent.
