Answer 1

Answer:

90 is the answer......................... ok

Answer 2

Answer:

The correct answer is 90.

Step-by-step explanation:

Step 1:

First, we have to write the table of 9.

The table of 9 is:

9 x 1 = 9

9 x 2 = 18

9 x 3 = 27

9 x 4 = 36

9 x 5 = 45

9 x 6 = 54

9 x 7 = 63

9 x 8 = 72

9 x 9 = 81

9 x 10 = 90

Step 2:

Now, we have to double the table of 9.

By doubling the table of 9, we will get table of 18.

Hence, the table of 18 is:

18 x 1 = 9 x 2 = 18

18 x 2 = 18 x 2 = 36

18 x 3 = 27 x 2 = 54

18 x 4 = 36 x 2 = 72

18 x 5 = 45 x 2 = 90

18 x 6 = 54 x 2 = 108

18 x 7 = 63 x 2 = 126

18 x 8 = 72 x 2 = 144

18 x 9 = 81 x 2 = 162

18 x 10 = 90 x 2 = 180.

Step 3:

As we can see, the product 18 x 5 is 90.

Hence, the answer is 90.
