Stels [109]1 year ago
4 0

Answer:

Step-by-step explanation:

400*60% can be rewriten as 400×0.6 which is 240, so a is false.

the same steps can be repeated for b and c

b) 200*0.6=120, therefore is false

c) 120*0.6=72, therefore is false

2)

60 percent * x=87\\0.6x=87\\x=\frac{87}{0.6} \\\\x=145

Now we check the answer by using the same steps in problems a,b,c

145*0.6=87\\87=87

3)

0.6c=43.2\\c=\frac{43.2}{0.6} \\c=72

and finally

0.38e=190\\e=\frac{190}{0.38} \\e=500
