The product of two rational numbers is 1556 if one of the number is - 548 find the other

Answer:

We know that the product of two rational numbers = -8/9

One of the number = -4/15

∴ other number is obtained by dividing the product by the given number.

Other number = (-8/9)/(-4/15)

= (-8/9) × (15/-4)

= (-2/3) × (5/-1)

= (-2×5) /(3×-1)

= -10/-3

= 10/3

hello everybody welcome to leader learning my name is rachna chaudhary and we are going to solve this question question is the product of two rational numbers is minus 8 upon 9 one of the numbers is minus 4 upon 15 so let's note down whatever is given so the product is minus 8 upon 9 first number is minus 4 upon 15 we have to find the second number so second number can be obtained by dividing the product by the first number product is minus 8 upon 9 second number is minus 4 upon 15 we are going to use keep change flip keep change flip so keep minus 8 upon 9 as it is change division into multiplication flip the next fraction so 15 upon minus 4 minus 4 is n minus 8 are cancelled out by each other so we know 2 times now we can also cancel out 9 and 15 by 3 because 3 is a common factor so 3 times 3 is 9 3 times 5 5 is 15. now we have to multiply numerators to the numerators and denominator to the denominator so 2 multiplied by 5 10 3 multiplied by one we have one here so we have three this is the final answer i hope you understand the method see you in my next video don't forget to like share and subscribe the channel thank you for watching
