Question

Please answer correctly

I will mark brainlist who will give answer properly ​

Answer 1

Answer:

ACTUALLY I DID NOT UNDERSTAND THE 3RD QUESTION

Step-by-step explanation:

1]MULTIPLICATIVE INVERSE

6/7   ----->7/6

-7/25--------> -25/7

2]INSERT TWO FRACTIONS BETWEEN

1]4/7 AND 8/9

lcm of 9 and 7 is 63

$\frac{4*9}{7*9} \\\frac{36}{63} \\\frac{8*7}{9*7} \\\frac{56}{63}$

* symbol denotes multiplication

answer=37/63 and38/63

2]7/8 AND 3/4

lcm of 8 and 4 is 8

$\frac{7*1}{8*1} =\frac{7}{8} \\\frac{3*2}{4*2} =\frac{6}{8}$

as there is only 1 digit between then you have to multiply it by 10

$\frac{7*10}{8*10} =\frac{70}{80} \\\frac{6*10}{8*10} =\frac{60}{80}$

answer = 61/80 and 62/80

i am sure that these are the answer...

hope it helps you...mark brainlist....

Answer 2

1) Write multiplicative inverse :

a) 6/7

b) -7/25

Answer :

$1 ) \: \tt{\blue{ \frac{6}{7} = \frac{7}{6} }}$

$2 \: ) \tt{\blue{ \frac{ - 7}{25} = \frac{25}{ - 7} }}$

Note :

What is multiplicative inverse ?

= It means to reciprocal the given question so that if when multiplied to it's original numbers yeilds 1 .

2) Insert two fraction between :

a) 4/7 and 8/9

b) 7/8 and 3/4

Answer ;

a) first make their denominator same by LCM .

So 7 and 9 LCM = 63

$1) \: \tt{\pink{ \frac{4}{7} = \frac{36}{63} \: \: \: \: \: \: \frac{8}{9} = \frac{32}{63} }}$

$\therefore \tt{\red{two \: fraction \: = \green{\frac{33}{63}} \: \: \green{\frac{35}{63} }}}$

b ) First again make their denominator same by LCM.

So 8 and 4 LCM = 16

$2) \: \tt{\purple{ \frac{7}{8} = \frac{14}{16} \: \: \: \: \: \: \frac{3}{4} = \frac{12}{16} }}$

$\therefore \tt{\red{two \: fraction \: = \green{\frac{13}{16}} \: \: \green{\frac{14}{16} }}}$

3 ) Write the names of all brackets used in a simplification :

Answer :

$1) \: (—) \tt{ \pink{ \: bar \: bracket}}$

$2) \: (()) \tt{ \pink{ \: small \: bracket}}$

$\3) ( {} ) \tt{ \pink{curley \: bracket}}$

$4) \: ( [ \: ]) \tt{ \pink{big \: bracket}}$
