Four fifths of 60 is equivalent to ()% of 80, and 15 meters is () meters after adding one third of him Put 25 grams of salt into 100 grams of water, the salt content of salt water is ()% The scale of a map is 1:100000. 1.5cm on the map represents actual () km From school to children's palace, the time ratio of Li Ming and Wu Dong is 3:5, and the speed ratio is ()

Four fifths of 60 is equivalent to (60)% of 80. When 15 meters is increased by one third, it is (20) meters. Put 25 grams of salt into 100 grams of water, and the salt content is (20)%. The scale of a map is 1:100000, and 1.5 cm on the map represents the actual (1.5) kilometers

(1-three fifths) x + 5 = 80% x how to solve this equation!

(1-three fifths) x + 5 = 80% X
0.4x+5=0.8x
0.8x-0.4x=5
0.4x=5
x=5÷0.4
x=12.5

The number 60% more than a number is 5:8, find the number and solve the equation

Let this number be X
（1+60%）x=8/5
8x/5=8/5
x=1
