Let's solve each ratio problem step by step based on the image provided. We'll count the number of each symbol and then compute the required ratios.

Problem 1: Hearts (♥) and Plus Signs (+)
Image:
- Rows of hearts (♥) and plus signs (+)
- Each row has 4 hearts and 8 plus signs
- There are 5 rows
So:
- Total ♥ = 5 × 4 =
20
- Total + = 5 × 8 =
40
####
(a) Ratio of ♥ to +
- Ratio = 20 : 40
- Simplified: divide both by 20 →
1 : 2
####
(b) Ratio of + to (♥ + +)
- Total symbols = 20 + 40 = 60
- Ratio of + to total = 40 : 60
- Simplified: divide by 20 →
2 : 3
✔ Answer 1:
- ♥ to + =
20 : 40 = 1 : 2
- + to (♥ + +) =
40 : 60 = 2 : 3

Problem 2: Black Circles (●) and Orange Crosses (✚)
Image:
- Grid of black circles (●) and orange crosses (✚)
- The grid is 7 rows high, 9 columns wide
- Count:
- ●: First 7 columns in all 7 rows → 7×7 =
49
- ✚: Last 2 columns → 7×2 =
14
Wait — actually, looking carefully:
The pattern:
- 7 columns of ● and 2 columns of ✚
- So:
- ● = 7 columns × 7 rows =
49
- ✚ = 2 columns × 7 rows =
14
####
(a) Ratio of ● to ✚
- 49 : 14
- Simplify: divide by 7 →
7 : 2
####
(b) Ratio of ✚ to (● + ✚)
- Total = 49 + 14 = 63
- ✚ : total = 14 : 63
- Simplify: divide by 7 →
2 : 9
✔ Answer 2:
- ● to ✚ =
49 : 14 = 7 : 2
- ✚ to (● + ✚) =
14 : 63 = 2 : 9

Problem 3: Black Diamonds (◆) and Blue Triangles (▲)
Image:
- Two rectangles side by side
- Left: 6 rows × 7 columns = 42 ◆
- Right: 6 rows × 8 columns = 48 ▲
Wait — let’s check:
- Both rectangles have 6 rows
- Left rectangle: 7 columns of ◆ → 6×7 =
42
- Right rectangle: 8 columns of ▲ → 6×8 =
48
####
(a) Ratio of ◆ to ▲
- 42 : 48
- Simplify: divide by 6 →
7 : 8
####
(b) Ratio of ▲ to (◆ + ▲)
- Total = 42 + 48 = 90
- ▲ : total = 48 : 90
- Simplify: divide by 6 →
8 : 15
✔ Answer 3:
- ◆ to ▲ =
42 : 48 = 7 : 8
- ▲ to (◆ + ▲) =
48 : 90 = 8 : 15

Problem 4: Orange Crosses (✚) and Red Circles (●)
Image:
- Two groups:
- Left: 5 rows × 8 columns = 40 ✚
- Right: 5 rows × 4 columns = 20 ●
So:
- ✚ = 40
- ● = 20
####
(a) Ratio of ✚ to ●
- 40 : 20 =
2 : 1
####
(b) Ratio of ● to (✚ + ●)
- Total = 40 + 20 = 60
- ● : total = 20 : 60 =
1 : 3
✔ Answer 4:
- ✚ to ● =
40 : 20 = 2 : 1
- ● to (✚ + ●) =
20 : 60 = 1 : 3
