Let's simplify step-by-step.

2n−9−(−2.4n+4)

Write 9.753 in words
vlabodo [156]
Hey there! :D

When you write out decimals, you use words that end with 'ths'. And you use the smallest digit's place to name the whole decimal. 

For example,

.1 = one-tenths  .25= twenty hundreths .345= three hundred and forty five thousandths

9.753= Nine and seven hundred fifty-three thousandths. 

I hope this helps!
