23-17 - (- 7) + (- 16) 2 / 3 + (- 1 / 5) - 1 + 1 / 3
(26.54) ＋ (- 6.4) － 18.54 ＋ 6.4 (－ 4 and 7 / 8) － (- 5 and 1 / 2) ＋ (- 4 and 1 / 4) － 3 and 8 / 10 ＋ 1 － [(- 1) － (- 3 / 7) － (+ 5) - (- 4 / 7))] + - 4

(26.54) + (- 6.4) - (18.54) + 6.4 change the position, the original formula = - 26.54-18.54 = - 45.08 (- 4.8 / 7) - (- 5.2 / 1) + (- 4.4 / 1) - (3.8 / 1) = (- 4.8 / 7) - (3.8 / 1) - [(- 5.2 / 1) + (- 4.4 / 1)] =

The simple algorithm of 17 / 48 × 49 the reciprocal of a number is 3 / 4, so what is its 5 / 16

17 / 48 × 49
=17/48*(48+1)
=17+17/48
=17 and 17 / 48
If the reciprocal of a number is three fourths, what is five sixteenth
The reciprocal of a number is three quarters, and the number is four thirds
4/3*5/16=5/12
If the reciprocal of a number is three fourths, then five sixteenth of a number is 5 / 12
