How to calculate such expressions as a × B + a? For example, two fifths × nine + two fifths (using the ladder equation)
A×B＋A
=A*(B+1)
Two fifths × nine + two fifths
=2/5*(9+1)
=2/5*10
=4
Use the fraction with the same denominator to form the formula and calculate 1 / 4 1 / 4 3 / 9 3 / 9 4 / 5 4 / 5 2 / 9 25
One ninth one ninth seven
1/4+3/4=4/4=1
3 / 9 + 4 / 9 + 2 / 9 + 1 / 9 + 7 / 9 = 17 / 9 = 1 and 8 / 9
4 / 5 + 2 / 5 + 1 / 5 = 7 / 5 = 1 and 2 / 5
I don't know the answer is satisfactory? I wish you progress in your study!
What's the difference between dividing 2 by 10 / 7 and subtracting the reciprocal of 7? Thank you,
Let the difference be X.2 △ 70% - 7 = x, x = 19 / 7
