2.28÷{3.76+2.3-(0.7÷7/9×5/3)}
first turn 0.7 into a fraction > 7/10
then divide 7/10 and 7/9 > 7/10 / 7/9 > flip 7/9 and multiply 7/10 by its reciprocal > 7/10 x 9/7 = 9/10
the equation should now look like this
2.28÷{3.76+2.3-(9/10×5/3)}
next multiply 9/10 and 5/3 to get 3/2. now turn 3/2 into a decimal. > 1.5
2.28÷{3.76+2.3-(1.5)}
now add 3.76+2.3 to get 6.06.
2.28÷(6.06-1.5)
subtract 1.5 from 6.06 to get 4.56
2.28÷4.56 = 0.5
0.5 is your answer
