5 out of 9 times 6.3 + 5 out of 9 times 14.2 minus 5 out of 9 times 2.5 fast

5 out of 9 times 6.3 + 5 out of 9 times 14.2 minus 5 out of 9 times 2.5 fast


5 out of 9 times 6.3 + 5 out of 9 times 14.2 minus 5 out of 9 times 2.5
=5x (6.3 + 14.2-2.5)
=5x18 / 9
=10



There are () one-third in five, and () one ninth in four and two-thirds
And said why. The five points belong to him!
There's another problem. Write three true fractions with only one fraction unit difference. The false fraction with fraction is ()


There are (15) one-third of them, four and two-thirds of them and (42) one ninth of them
5=15/3
4 2/3=14/3=42/9
6/7 7/7 1 1/7



Solving the equation 6 / 7 x + 1 / 8 = 2 / 9


Six out of seven x + one out of eight = two out of nine
6/7x=2/9-1/8
6/7x=7/72
x=7/72÷ 6/7
x=7/72*7/6
x=49/432



Solving the equation: 7 / 9 / x = 1 / 8 / 9 / 40


7/9 / x = 1/8 / (9/40)
7/9 * 9 / 40 = 1/8x
7/40 = 1/8 x
x = 7/5



One third (9 and two fifths - 3) + 6 [two thirds x (- nine tenths) + 1]


One third (9 and two fifths - 3) + 6 [two thirds x (- nine tenths) + 1]
=1 / 3x6 and 2 / 5 + 6x (- 3 / 5 + 1)
=1/3x32/5+6x2/5
=32/15+12/5
=32/15+36/15
=68/15
