solve:
1 (3/8+1/4) x16
2 72 divided by (7-1) x 3
3 5/6 - 4 x 1/12
4 32 divided by (2.3 +1.7) x 3
5 (6.3 - 5.1) x (0.7+0.3)
6 1/2 x 1/2 divided by 1/2

1. 10

2. 4

3. 0.51

4. 2.67

5. 1.2

6. 0.5

Step-by-step explanation:

1. 3/8 + 2/8 = 5/8 = 0.625

0.625 * 16 = 10

2. 7 - 1 = 6

6 * 3 = 18

72/18 = 4

3. 1/12 = 0.08

4 * 0.08 = 0.32

5/6 = 0.83

0.83 - 0.32 = 0.51

4. 2.3 + 1.7 = 4

4 * 3 = 12

32/12 = 2.67

5. 6.3 - 5.1 = 1.2

0.7 + 0.3 = 1

1.2 * 1 = 1.2

6. 0.5 * 0.5 = 0.25

0.25/0.5 = 0.5

there is no grid
