-2/9 x 1/7
To multiply two fractions, you simply need to multiply the numerators together and the denominators together.
For -2/9 x 1/7:
(-2 x 1) / (9 x 7)
= -2/63
Explain how you got your answer step by step
Sure! Let's break it down step by step.
We have the fraction -2/9 multiplied by the fraction 1/7.
Step 1: Multiply the numerators: -2 x 1 = -2.
Step 2: Multiply the denominators: 9 x 7 = 63.
So, the answer is (-2/63).
Alternatively, you can perform the multiplication first and then simplify the fraction:
Step 1: Multiply the numerators: -2 x 1 = -2.
Step 2: Multiply the denominators: 9 x 7 = 63.
Step 3: Combine the results from Step 1 and Step 2 to get the answer: -2/63.
So, the answer is also -2/63.
7 x -4 step by step
Sure! Let's break it down step by step.
We have the multiplication 7 x -4.
Step 1: Multiply the numbers: 7 x -4 = -28.
So, the answer is -28.
Alternatively, we can break it down using the concept of multiplication by a negative number:
Step 1: Multiply the absolute values: 7 x 4 = 28.
Step 2: Apply the negative sign: Since one of the numbers is negative, the result will be negative.
Therefore, the answer is -28.
Both methods will give you the same result, which is -28.
-28 x -19 step by step
Sure! Let's break it down step by step.
We have the multiplication -28 x -19.
Step 1: Multiply the numbers: (-28) x (-19) = 532.
So, the answer is 532.
Alternatively, we can break it down using the concept of multiplication by two negative numbers:
Step 1: Multiply the absolute values: 28 x 19 = 532.
Step 2: Apply the rule for multiplying two negative numbers: When you multiply two negative numbers, the result is positive.
Therefore, the answer is 532.
Both methods will give you the same result, which is 532.
