D)3.6/7*0.08/1.1*2.2/1.2*2.1/0.6=

Answer 1

A) 1/6*3[3/4]*100*4/15*24/25= 1/6*15/4*100/1*4/15*24,25=16/1=16

B)0.4*1.4*3/4*1/7*10=2/5*7/5*3/4*1/7*10=18/16=1i 2/16= 1 i 1/8

C)6.6*9/40*5/6*8/11*1/3=33/5*9/40*5/6*8/11*1/3=9/30=3/10

D)3.6/7*0.08/1.1*2.2/1.2*2.1/0.6=3*0,08=0,24

Answer 2

a)(¹/₆*²⁴/₂₅)*100*(3 ¾*⁴/₁₅)=(⅙*²⁴/₂₅)*100*(¹⁵/₄*⁴/₁₅)=⁴/₂₅*100*1=16

b)(³/₄*¹/₇)*10*0.4*1.4=3/28*4*1,4=3/7*14/10=6/10

c)1/3* (5/6 *  ( 9/40 * 8/11 * 6.6))=1/3* (5/6 * (9/55 *66/10))=1/3* (5/6 * 54/50)=

1/3 * 9/10=3/10

d)  8/110* (22/12 *(36/70 * 21/6))= 8/110 *(22/12 * 18/10)=8/110*33/10=0,24
