Express each ratio as a fraction in its simplest form:
8 dm to 3.2m

Step-by-step explanation:

8 dm to 3.2m

80dm to 32m (multiplying by 10)

= 5dm to 2m (dividing by 16)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
