Find "G". Round to two decimal places. G= R+ab/at R=257 a=4.88 b=37.4 t=61.5

givi [52]

Answer:

G ≈ 1.46

Step-by-step explanation:

Given

G = $\frac{R+ab}{at}$ , substitute values

G = $\frac{257 4.88(37.4)}{4.88(61.5)}$

= $\frac{257+182.512}{300.12}$

= $\frac{439.512}{300.12}$ ≈ 1.46 ( to 2 dec. places )

Which is bigger 0.45 or 2/5

pickupchik [31]

The biggest out of the two possible answers is 0.45. 2/5 in decimal form is 0.4, or in percentage form becomes 40%. However, if 0.45 is changed into a fraction, it becomes 9/20 in its smallest form, which is difficult to compare. If we consider 0.45 as a percentage, however, it obviously becomes 45%, which is bigger than 40% so we can confirm that 0.45 is larger than 2/5.
