2/3 bc it can be a boy and a girl a girl and a girl a boy and a boy
Answer:
5 : 4
Step-by-step explanation:
To simplify the ratio , find the greatest common factor of 60 and 48, then divide both parts of the ratio by it
the greatest common factor of 60 and 48 is 12, hence
60 ÷ 12 : 48 : 12 = 5 : 4 ← in simplest form
Answer:
B. 
Step-by-step explanation:
9514 1404 393
Answer:
a) 230
b) 300
c) 2×10^-2
d) 1.1×10^-6
Step-by-step explanation:
a) 0.26 × 890 ≈ 1/4 × 900 ≈ 225 ≈ 230
b) 1.95/(.67×10^-2) ≈ 2/(2/3)×10^2 ≈ 300
c) 2010×10^-5 ≈ 2×10^3×10^-5 = 2×10^-2
d) 9.98×10^-4/(9×10^2) = 9.98/9×10^(-4-2) ≈ 1.1×10^-6

YMMV depending on how you do the rounding and approximate multiplication and division.
The first one can be done multiple ways. For most accurate results, increasing one number while decreasing the other is recommended. (You don't want to compute 0.3×900, for example.)
