giúp mink với ạ. Mình đang cần gấp

Answer 1

a: \(=\dfrac{1.8\cdot4.5}{0.25}\cdot\dfrac{1.4}{4.2}+4.33=\dfrac{32.4}{3}+4.33=10.8+4.33=15.13\)

b: \(=1003.55-3.55-999=1000-999=1\)

c: \(=3.78\left(200-68-100+68\right)=100\cdot3.78=378\)

d: \(=0.1\cdot\dfrac{\left(4.8+1.5\right)\cdot\left[\left(4.8-1.5\right):0.3+1\right]}{2}=3.78\)
