Given that 99=100 -1,calculate the value of 152 x 99.
152 x 99= 152(100-1)=15200-152=....15048
I don't understand the question
Oh boy, math time! Well, based on your equation where 99 = 100 - 1, let's use some mathematical magic to solve 152 x 99.
First, let's rewrite 99 as (100 - 1). Now, we can multiply 152 by (100 - 1) and use the distributive property to make things easier.
152 x (100 - 1)
= (152 x 100) - (152 x 1)
= 15,200 - 152
= 15,048
So, the value of 152 x 99, according to your equation, is 15,048.
To calculate the value of 152 x 99, we can use the property of distributivity. The property states that (a - b) x c is equal to (a x c) - (b x c).
So in this case, we have:
152 x 99 = (100 - 1) x 99
Using the distributive property, we can expand this expression as follows:
152 x 99 = (100 x 99) - (1 x 99)
Now, we can calculate the two parts separately:
100 x 99 = 9900
1 x 99 = 99
Substituting these values back into the equation, we get:
152 x 99 = 9900 - 99
Now, we can simply subtract 99 from 9900:
152 x 99 = 9801
Therefore, the value of 152 x 99 is 9801.
