3(0.4 - 0.6) X 1.5
Is this even possible.....you can't do 0.4 minus 0.6
You can it will become a negitive number use the distributive property and multiply the stuf after you complete parenthases.
so first subtract 0.6 from 0.4 that will be -0.2 then multiply that by 3 note the answer will be negitive than perform the rest. Answer whn your done so you can ;earn how to do these yourelf : )
