Let’s solve each part step by step.
---
Top Row (Grids with shaded parts):
Each grid is 10x10 = 100 squares total. So, the number of shaded squares is the numerator over 100.
1.
Green grid: Only 7 squares are shaded → 7/100 =
0.07
2.
Yellow-orange grid: Count carefully — first column full (10), second column has 8 → 10 + 8 = 18 → 18/100 =
0.18
3.
Red grid: Almost full — missing only 5 squares on right side → 100 - 5 = 95 → 95/100 =
0.95
---
Middle Row:
4.
Blue grid: First column has 6 shaded → 6/100 =
0.06
5.
Bright yellow grid: Missing only last row except one square? Wait — let’s count:
It’s 9 full rows (90) plus 9 in the 10th row → 90 + 9 = 99 → 99/100 =
0.99
6.
Purple grid: Only 2 squares shaded at top left → 2/100 =
0.02
---
Bottom Section: Convert fractions to decimals or vice versa
7.
4/10 → Divide 4 by 10 → move decimal point one place left →
0.4
8.
? / 10 = 0.8 → 0.8 means 8 tenths → so numerator is
8
9.
7/100 → 7 hundredths →
0.07
10.
? / 100 = 0.75 → 0.75 means 75 hundredths → numerator is
75

Final Answer:
Top row:
7/100 = 0.07
18/100 = 0.18
95/100 = 0.95
Middle row:
6/100 = 0.06
99/100 = 0.99
2/100 = 0.02
Bottom section:
4/10 = 0.4
8/10 = 0.8
7/100 = 0.07
75/100 = 0.75
