Question

Which calculation results in the best estimate of 148% of 203?
(200) (140 percent) = (200) (100 percent + 40 percent) = (200) (100 percent) + (200) (40 percent) = (200) (1.0) + (200) (0.4) = 200 + 80 = 280
(210) (140 percent) = (210) (100 percent + 40 percent) = (210) (100 percent) + (210) (40 percent) = (210) (1.0) + (210) (0.4) = 210 + 84 = 294
(200) (150 percent) = (200) (100 percent + 50 percent) = (200) (100 percent) + (200) (50 percent) = (200) (1) + (200) (one-half) = 200 + 100 + 300
(210) (150 percent) = (210) (100 percent + 50 percent) = (210) (100 percent) + (210) (50 percent) = (210) (1) + (210) (one-half) = 210 + 105 = 315

Answer 1

$200(140\%)$

$= 200(100\% + 40\%)$

$= 200(100\%) + 200(40\%)$

$= 200(1) + 200(0.4)$

$= 200 + 80$

$= 280$

$210(140\%)$

$= 210(100\% + 40\%)$

$= 210(100\%) + 210(40\%)$

$= 210(1) + 210(0.4)$

$= 210 + 84$

$= 294$

$200(150\%)$

$= 200(100\% + 50\%)$

$= 200(100\%) + 200(50\%)$

$= 200(1) + 200(0.5)$

$= 200 + 100$

$= 300$

$210(150\%)$

$= 210(100\% + 50\%)$

$= 210(100\%) + 210(50\%)$

$= 210(1) + 210(0.5)$

$= 210 + 105$

$= 315$

Answer 2

Answer:

300.45

Step-by-step explanation:

use the percentage formula(p%×y=x)

step1

p%×y=x

step2

here p= 148

y=203

Now the equation solve the problem

p%×y=x

convert148%0to fraction to convert percent just remove percent devided by 100

step4

148/100*203=x

step5

x=148/100*203

x=148*203/100

30044/100=300.44

then ans 300.44
