Answer:
27/50 or 0.54
Step-by-step explanation:
For solving this question we have to follow BODMAS(Bracket of Division Multiplication Addition and Subtraction) here.
=>[7/9-{7/9-(7/9-4/9)}]of 1.8-0.6÷10 at first we will solve the small bracket () and the L.C.M of the denominators are same so we will simply subtract the numerators
=>[7/9-{7/9-3/9}] of 1.8-0.6÷10 now in this we will solve curly bracket{} in this also the denominators are same so we simply subtract the numerators
=>[7/9-4/9] of 1.8-0.6÷10 in tis step we will solve the square brackets [] again the denominators are same so we again solve the numerators
=>3/9 of 1.8-0.6÷10 now we will change the of into multiplication sign(x) and we will change all the decimals into fractions
=>3/9 x 18/10-6/10÷10/1 now we will reduce all the fractions
=>1/3 x 9/5 - 3/5÷10/1 now we will divide according to the rule of BODMAS and for the division we have to do the reciprocal of 10/1 and it will become 1/10
=>1/3 x 9/5-3/5 x 1/10 now we will multiply 3/5x1/10
=>1/3 x 9/5-3/50 now we will multiply according to rule of BODMAS
=>9/15-3/50 now we will reduce 9/15 and it will come 3/5
=>3/5-3/50 now we will find out the LCM of 5 and 50 is 50 so will change the denominators of the fraction equal to 50.
=> 30-3/50 now we will subtract the numerators
= 27/50 this is our answer and if you want to change into decimal it has changed below
=0.54
