Question

Find 3 upon 7 + 6 upon 11 divided( minus 8 upon 21)

Answer 1

Answer:

here it is

3/7 + 6/11 ÷ ( – 8/21 )

first taking the lcm of 3/7 and 6/11 we get

= 33+42/77 = 75/77

now dividing with – 8/21

= 75/77 ÷ ( – 8/21 )

= 75/77 / - 8/21

now by repricol 75/77 will remain same but - 8/21 will get repricol as - 21/8 and also it will get multiplied with 75/77

= 75/77×( - 21/8 )

= - 1575 / 616
