5.6$
we have 1 yaun=0.13 euro
1 euro=1.09 dollars
so first we will convert 40 yuan into euros for that we have l yaun=0.13 euro from this if l yaun=0.13 euro then how much is 40 yuan
l yaun=0.13 euro
40 yuan = ?
crisscross then we get
?=40yuan×0.13euro÷1yuan
?=5.2 euros
1euros =1.09 dollars
5.2euros =?
?=5.2 euros ×1.09$÷1euros
?=5.67$
