We know that 7/10 of the cookies are chocolate chip, so that means there are 3/10 of the cookies left.
We now want to find what 3/4 of 3/10 is.
We can do this by multiplying both fractions
3/4x3/10 (we just multiply across) to get 9/40.
We cannot simplify this answer, so our final answer is 9/40 of the cookies are sugar cookies.

104 km=_ m?<br> 480cm=_ m?<br> 5.6kg=_ g?<br> 8mm=_ cm?

Anastasy [175]

$1km=1,000m\\therefore\ 104km=104\times1,000m=\boxed{104,000m}\\\\1m=100cm\to1cm=0.01m\\therefore\ 480cm=480\times0.01m=\boxed{4.8m}\\\\1kg=1,000g\\therefore\ 5.6kg=5.6\times1,000g=\boxed{5,600g}\\\\1cm=10mm\to1mm=0.1cm\\therefore\ 8mm=8\times0.1cm=\boxed{0.8cm}$
