Solve 9/10=z/9 . round to the nearest tenth. 7.2 10.1 11.3 8.8

Remark

None of them are correct.

Solve

9/10 = z/9     Since 9 is smaller than 10 (both in the denominator), the answer(z) should be smaller than the nine in the numerator. That means that the second and third answers are incorrect. To find z, multiply both sides by 9

(9/10) * 9 = (z/9)*9

9/10 * 9 = z

9*9/10 = z

81/10 = z

z = 8.1

the last one is the closest, but there is no real answer.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

( give brainliest)

i think that you should ask google for the answer to that problem because if we don't know it google does
