Question

Д) 15.3 * 4 : 9 + 3.2 = ? е) (4.3 + 2.4 : 8) * 3 = ? ж) 280.8 : 12 - 0.3 * 23 = ?​

Answer 1

Ответ:

д) 15.3*4:9+3.2=10

15.3*4=61.2

61,2:9=6.8

6.8+3,2=10

Е) (4.3 + 2.4 : 8)*3 =13,8

2,4:8=0,3

0.3+4,3=4,6

4.6*3=13,8

ж) 280.8:12-0.3*23=16.5

280,8:12 =23,4

0.3*23=6.9

23,4-6,9=16,5

Answer 2

Ответ:

д)61,2:9+3,2=6,8+3,2=10

е)4,6*3=13,8

ж)23,4-6,9=16,5

Answer 3

Let's solve the given mathematical expressions step by step:

Д) 15.3 * 4 : 9 + 3.2

Step 1: Multiply 15.3 by 4 15.3 * 4 = 61.2

Step 2: Divide the result by 9 61.2 : 9 = 6.8

Step 3: Add 3.2 to the result 6.8 + 3.2 = 10

So, Д) 15.3 * 4 : 9 + 3.2 = 10

е) (4.3 + 2.4 : 8) * 3

Step 1: Divide 2.4 by 8 2.4 : 8 = 0.3

Step 2: Add 4.3 to the result 4.3 + 0.3 = 4.6

Step 3: Multiply the result by 3 4.6 * 3 = 13.8

So, е) (4.3 + 2.4 : 8) * 3 = 13.8

ж) 280.8 : 12 - 0.3 * 23

Step 1: Divide 280.8 by 12 280.8 : 12 = 23.4

Step 2: Multiply 0.3 by 23 0.3 * 23 = 6.9

Step 3: Subtract the result from Step 2 from the result of Step 1 23.4 - 6.9 = 16.5

So, ж) 280.8 : 12 - 0.3 * 23 = 16.5
